ZKP are used in the covid vaccination passport systems for both The Netherlands and New Zealand. Ours (I'm part of the NL team) is open source: https://github.

  It seems likely you are just trying to get a rise out of people, but I'll bite: Which tech do you mean, and what do you think makes it terrible?

    I think that he's confusing "crypto" - as in the Ponzai scheme - with cryptographic techniques. The latter is very interesting and has real world applications. The former is a scam which is making a small group very rich and will eventually wipe out a load of suckers.

      Okay, why do you think those are terrible though? Aren't they a useful tool, provided they are implemented in a privacy-preserving manner (which I suspect the ZK-proof implementation is all about)?

Where can I read more about ZKP in the context of your project? I went through the repo but could not find anything related to ZKPin there.

  The documentation isn't that great, but the implementation is here: https://github.com/minvws/nl-covid19-coronacheck-idemix https://github.com/minvws/nl-covid19-coronacheck-idemix We use IDEMIX to create a unique proof per display of the QR code. So you cannot track a person as they use their QR code (if you have control of a network of scanner apps).

    That sounds, in theory, like a pretty cool use for ZKP. However, I'm skeptical how you fulfil the other requirements that vaccine QR codes generally have without also providing a workaround for tracking. For instance, most vaccine QR codes are not considered valid by themselves, as I could simply share my QR code with my friend. So I need to present valid photo ID alongside the QR code.

I’m in NZ. Can you link the source for NZ using zero knowledge proofs? Very curious to read it thanks

I'm the author of one of the open source NZ vaccination passport libs. I'm pretty familiar with the specification and afaik I know theres no use of ZKP's. Its a fairly standard public/private key cryptography. Happy to be proven wrong though! Here's the spec: https://nzcp.covid19.health.nz/ https://nzcp.covid19.health.nz/ and our implementation https://github.com/vaxxnz/nzcp-js https://github.com/vaxxnz/nzcp-js

  I'm indeed wrong, I had understood from a discussion with someone involved in the project that it was so :) Just had a chat with my buddies at mattr who corrected me :)

Any chance you are looking for more members - at least on the web aspect?
